Philadelphia -- It's another week and another enormous challenge for New Orleans Saints rookie left tackle Terron Armstead.

Armstead, who will be making his initial playoff appearance Saturday against Philadelphia in just his third start, will have his hands full taking on Eagles veteran outside linebacker Trent Cole a good part of their NFC wild-card matchup.

Cole has certainly taken notice of the youngster, who was elevated over veteran Charles Brown after the loss at St. Louis. The Eagles' regular-season sacks leader is clearly looking at Saturday night as an opportunity.

"He's very athletic, but he's got some weak spots," said Cole, who had eight sacks, 15 quarterback pressures and 10 tackles for loss during the regular season and ranks second on the team's all-time career sacks list with 79. "That's the thing, man, going into the game you take advantage of them. I see they helped him out with a bunch of chips and stuff, and it's helped out.

"But it's a challenge for him, and it's a challenge for me. Every game is different, every player is different."

When asked if he expects the Saints to provide Armstead help against him Saturday, Cole replied, "They'd better."

Ryan has a knack for creating confusion with constant movement along his defensive front to gain favorable matchups. And it has been a huge success for the Saints, who ranked fourth in the NFL with 49 sacks during the regular season.

Defensive end Cameron Jordan (12½ sacks) and outside linebacker Junior Galette (12) ranked fifth and sixth in sacks, respectively, in the league this season.

Those are all facts that aren't lost on Kelly and his coaching staff as they prepare for Saturday night's game.

"Rob does a real good job of getting them matched up in certain situations," Kelly said. "They are not always in the same spot so you just can't come out and say, 'Hey, that guy is the left defensive end and we know where he is.' He's going to move them around. And then with all the blitz packages that he does bring, they get singled up a lot and when they get singled up, they exploit that."

The Eagles might seem especially susceptible after allowing Foles to be sacked five times during Sunday's regular-season finale win over the Dallas Cowboys. But Eagles offensive coordinator Pat Shurmur doubts that has inspired Ryan to dial up even more blitz packages.

The Eagles' quick-tempo offense could neutralize Ryan's aggressive nature, which involves shuttling players in and out of the lineup between snaps. But Kelly isn't sure that will completely solve the problem.

"I think teams have done a good job of matching up when we get lined up fast," he said. "They are still being able to bring what they want to bring ...

"People know what we are trying to do, but they do a good job of still trying to get their packages in and execute them. But we are aware of that and hopefully we are calling the right plays that can handle what they are bringing at a certain time."

No satisfied with just making the playoffs: While few people expected the Eagles to be anywhere near the playoffs, running back LeSean McCoy said the team prepared to be in the position they are in as the NFC East champs after going 4-12 last season.

But McCoy said it would huge mistake for anyone to believe the Eagles are just happy making the playoffs. They are here to win.

McCoy says that is what Kelly has instilled in them in his first season.

"Coach Kelly is a new coach so I think his mentality coming in here has been just play hard every play and we are made for the playoffs," McCoy said. "Everybody is so excited for us to be here, but we should be here. Everybody is so excited about us being division champs, but I think we should be. We prepare hard each game. We have so much talent on this team and the way we prepare. We prepared to be the champs of the division, and we prepare to win this game.

"The Saints are a very good team for sure, a very explosive offense and a solid defense, but I think the guys in the locker room and the coaches we have, we can get the job done."
